APPARATUS FOR AUTOMATICALLY WASHING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 665,344, dated January 1, 1901.

Application filed April 2, 1900.

T0 (0Z5 whom it may concern:

Be it known that I, ANDERS ANDERSEN PINDSTOFTE, manufacturer, of Vesterbrogade 66, Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in or Relating to Apparatus for Automatically Washing Bottles and other Like Vessels, (for which I applied for patents in Denmark on the 31st of August, 1899, No. 946; in Sweden on the 2d of September, 1899, No.1,510; in Germany on the 2d of September, 1899, No. 10,917; in Norway on the 4th of September, 1899, No. 11,590; in France on the 9th of February, 1900, No. 285,239; in Belgium on the 15th of February, 1900, No. 116,723, and in England on the 13th of February, 1900, No. 2,885,) of which the following is a specification.

Apparatus for washing bottles and the like as heretofore constructed have been found to be inconvenient, as it is especially in that class wherein it is necessary for the bottle or the like to be maintained pressed onto the apparatus in order to cause it to act, inasmuch as the valve closed and the water-jet ceased directly the pressure was withdrawn.

My invention has for its object to construct a bottle or like washing apparatus which shall obviate such defects.

In carrying my invention into practice I provide means whereby the bottle or vessel on being placed upon the apparatus opens the valve thereof and keeps it open by its own weight until removed.

My invention is further designed to provide means whereby the pressure exerted by the water is caused to act upon a mechanical body, which when the valve is opened takes up a firmly-locked position in the direction of the valve motion, so that even the highest pressure ofwater in the conduit is unable to close such valve except when the latter is released by removing the bottle or other vessel from the apparatus.

The chief feature of my invention as compared with existing apparatus which do not produce the abovementioned effects consists in the arrangement of an intermediary link disposed between the extremity of the valverod and its operating-lever,which latter is depressed by the bottle placed on the apparatus and so opens the valve, while at the same time Serial No. 11,250. (No model.

moving into such a position as to prevent the valve being again closed until the lever is swung upward by removing the bottle from the apparatus.

In order that my invention may be readily understood and easily carried into effect, I will describe the same with reference to the accompanying drawings, in which Figure 1 is a longitudinal central section, and Fig. 2 a modified form, of a portion of the apparatus constructed in accordance with my invention.

The apparatus comprises a frame a, on which is mounted a valve-casing I), provided with a screwed extension 0, adapted to receive the water-supply pipe. The valve-casing is formed with a central passage 6, disposed in alinement with the water-pipe and normally held closed by a valve 9, arranged at one end of the valve-casing, which latter forms a seat for the valve. This Valve is pressed tightly against its seating by a helical spring 2', surrounding the valve-spindle h. This spiral spring is disposed between a pin Z, attached to the valve-spindle, and the first of two arms or bracketsm 'm, projecting from the frame and having holes drilled in them for the reception of the said valve-spindle. At the other end of the valve-casing the passage 6 is closed by a membrane as, to which leads the valve-spindle h, which is securely fastened thereto by means of a screwed sleeve y.

At right angles to the passage 6 is provided an outlet f, into which is screwed the jet-nozzle n. At the rear end of the frame a there is provided a pivotp, upon which is fulcrumed a two-armed lever q, of which the long arm takes around the jet-nozzle n, while the short arm carries a counterweight '2", having a tendency to cause the lever to return always to the dotted position in Fig. 1.

When placing a bottle or the like to be washed upon the nozzle 77., its weight will be sufficient to overcome the balance-weight r and to move the lever into the position shown in full lines in Fig. 1. On the lever q there is arranged a downwardly-curved arm s,t-o the lower extremity of which a link 11. is joined by means of a pivot-pin if, its free end resting against the rear end of the valve-spindle h where this latter projects through the bracket m. Thus when a bottle is placed on the nozzle n the lever q is depressed and the presserrod to advances and presses against the valvespindle hand so opens the valve. The water now flows through the passages c f into the nozzle n and finally into the vessel under the process of cleansing. When the vessel is removed, the counterweight 0' causes the leverarm q to return to the position shown in dotted lines in Fig. 1, and the spiral spring 1? then acts on the valve-spindle h, thus closing the valve.

Fig. 2 shows a slightly-modified form differing from that previously described by having its arm 8 pivotally connected to the leverarn1 q and carrying, besides the pivoted link it, a rearwardly-disposed link 10. By the depression of the lever q the link to is, through link 3, brought into line with the link it, so as to render them rigid, while at the same time the link to takes a footing against a projecting part of the frame, as shown in dotted lines in Fig. 2. The manner of operating the valve is the same as that hereinbefore described and as shown in Fig. 1.

As will be readily understood from the foregoing description, the valve after having been opened by the link it, which is then situated in a line with the valve-spindle, cannot be closed by even a high-water pressure, while yet closing automatically directly the bottle, vessel, or the like is removed from the apparatus.

' Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In apparatus of the character described, the combination of a valve-actuating rod, a valve-closure, or casing having a dischargepipe adapted to enter the article to be operated on, and a lever adapted to be engaged by said article and, itself, having a pivoted push-bar adapted to engage said valve-actuating rod, in such a manner that the axis of the valve-rod and the centers of rotation for both the lever and the push-bar form one straight line when the lever is pressed down through the weight of the article to be operated on, substantially as set forth.

2. In apparatus of the character described, the combination of a valve-actuating rod, a valve-casing having a discharge-pipe adapted to enter the article to be operated on, a lever adapted to be engaged by said article and,

itself, having a push-bar adapted to engage said valve-actuating rod, and means for automatically disengaging said push-bar from said actuating-rod, in such a manner that the axis of the valve-rod and the centers of rotation for both the lever and the push-bar form one straight line when the lever is pressed down through the weight of the article to be operated on, substantially as set forth.

3. In apparatus of the character described, the combination of a valve-actuating rod, a valve-casing having a discharge-pipe adapted to enter the article to be operated on, a lever having a weighted end and adapted to be engaged by said article, and, itself, having apivoted push-bar adapted to engage said valveactuating rod, in such a manner that the axis of the valve-rod and the centers of rotation for both the lever and the push-bar form one straight line when the lever is pressed down through the weight of the article to be operated on, substantially as set forth.

I. In apparatus of the character described, the combination ot'a valve-actuating rod with its valve adapted to automatically hold said valve closed or seated, a valve-casing having a discharge-pipe adapted to enter the article to be operated on, a weighted lever adapted to be engaged by said article and having, itself, a pivoted pushbar adapted to engage said valve-actuating rod, in such a manner that the axis of the valve-rod and the centers of rotation for both the lever and the pushbar form one straight line when the lever is pressed down through the weight of the article to be operated on, substantially as set forth.

5. In apparatus of the characterdescribed, the combination of a valve-actuating rod, a valve-casing having a discharge-pipe adapted to enter the article to be operated on, a lever having an additional arm adapted to be engaged bysaid article,a pivoted push-bar linked to said lever adapted to engage said valveactuating rod, and means for automatically disengaging said push-bar from said valveactuatiug rod, in such a manner that the axis of the valve-rod and the centers of rotation for both the lever and the push-bar form one straight line when the lever is pressed down through the weight of the article to be operated on, substantially as set forth.

I witness whereof I have hereunto set my hand in presence of two witnesses.
